Motor vehicle retractable roof comprising three sliding pivoting elements

ABSTRACT

The invention concerns a motor vehicle retractable roof, comprising a front roof element ( 1 ), an intermediate roof element ( 2 ) and a rear roof element ( 3 ). The displacement of the rear element ( 3 ) towards the rear deck is controlled by at least an arm articulated to the chassis and to the rear element. The invention is characterised in that the rear element ( 3 ) comprises a slide ( 9 ) extending between its front and rear edges wherein can be engaged a finger ( 10 ) integral with the rear edge of the intermediate element ( 2 ) so that the intermediate element ( 2 ) can slide on the rear element ( 3 ) and the intermediate element ( 2 ) also comprises a slide ( 11 ) extending between its front and rear edges wherein can be engaged a finger ( 12 ) integral with the rear edge of the front element ( 1 ) so that the front element ( 1 ) can slide on the intermediate element ( 2 ), and the front edge of the rear element ( 13 ) which is itself linked in articulation to the arm ( 6 ) by a hinge link ( 14 ) and the front edge of the intermediate element ( 2 ) is linked in articulation to the front element ( 1 ) through a lever ( 15 ) which is itself linked in articulation through a hinge link ( 16 ) with the lever ( 13 ) which links the intermediate element ( 2 ) to the front element ( 1 ).

[0001] The present invention concerns a roof which can be retracted or withdrawn into the rear boot of a vehicle.

[0002] Such a retractable roof makes it possible in particular to convert a vehicle of the two-seater coupe or four-seater coupe or saloon type into a vehicle of the cabriolet type.

[0003] In the case of four-seater coupes or saloons, the roof has a relatively long length, so that the retractable roof is composed of three elements, each of which has a length compatible with the dimensions of the vehicle boot.

[0004] Thus a retractable roof for a vehicle is known, comprising a front roof element, an intermediate roof element and a rear roof element, these three elements being able to move between a position in which they cover the vehicle cabin and a position in which they are superimposed substantially horizontally in the rear boot of the vehicle.

[0005] The aim of the present invention is to afford improvements to the known means, in order to optimally control and guide the movement of the roof elements between their closure position and their position of storage in the boot.

[0006] According to the invention, the retractable roof is characterised in that the movement of the rear element towards the boot is controlled by at least one arm articulated on the chassis of the vehicle and on the rear element, in that the rear element comprises a slide extending between its front and rear edges in which there can engage a finger fixed to the rear edge of the intermediate element so that the intermediate element can slide on the rear element, in that the intermediate element also comprises a slide extending between its front and rear edges in which there can engage a finger fixed to the rear edge of the front element so that the front element can slide on the intermediate element, in that the front edge of the rear element is connected in an articulated fashion to the intermediate element by means of a lever which is itself connected in an articulated fashion to the arm by a link and in that the front edge of the intermediate element is connected in an articulated fashion to the front element by a lever which is itself connected in an articulated fashion by a link to the lever which connects the intermediate element to the front element.

[0007] Other particularities and advantages of the invention will also emerge in the following description.

[0008] In the accompanying drawings, given by way of non-limiting examples:

[0009]FIG. 1 is a schematic view in partial longitudinal section of a vehicle equipped with a retractable roof according to the invention, in the closed position;

[0010]FIGS. 2 and 3 are views similar to FIG. 1 showing two versions of the retractable roof, the latter being in an intermediate position;

[0011]FIG. 3 is a view similar to FIG. 2 concerning a variant;

[0012]FIG. 4 is a view similar to FIGS. 1 to 3, the retractable roof being in a position stored in the vehicle boot.

[0013] In the embodiment depicted in FIGS. 1 to 4, the retractable roof comprises a front roof element 1, an intermediate roof element 2 and a rear roof element 3. These three elements 1, 2, 3 are able to move between a position in which (see FIG. 1) they cover the cabin 4 of the vehicle and a position in which (see FIG. 4) they are superimposed substantially horizontally in the rear boot 5 of the vehicle.

[0014] According to the invention, the movement of the rear element 3 towards the boot 5 is controlled by an arm 6 articulated at 7 on the chassis of the vehicle and at 8 on the rear element 3.

[0015] It can be seen in FIG. 2 that the rear element 3 comprises a slide 9 extending between its front 3 a and rear 3 b edges, in which there can engage a finger 10 fixed to the rear edge 2 a of the intermediate element 2 so that this intermediate element 2 can slide on the rear element 3.

[0016] The intermediate element 2 also comprises a slide 11 extending between its front and rear 2 a edges, in which there can engage a finger 12 fixed to the rear edge a of the front element 1 so that this front element 1 can slide on the intermediate element 2.

[0017] In addition, the front edge 3 a of the rear element is connected in an articulated fashion to the intermediate element by a lever 13 which is itself connected in an articulated fashion to the arm 6 by a link 14.

[0018] Moreover, the front edge of the intermediate element 2 is connected in an articulated fashion to the front element 1 by a lever 15 which is itself connected in an articulated fashion by a link 16 to the lever 13 which connects the intermediate element 2 to the rear element 3.

[0019] In the examples depicted in FIGS. 1 to 4, the movement of the rear element 3 towards the boot 5 is also controlled by a finger 17 carried by the rear part 3 b of the rear element 3 slidably engaged in a slide 18 extending inside of the boot 5.

[0020] Instead of this finger 17 and this slide 18, the movement of the rear element 3 towards the boot 5 can be controlled by a second arm articulated on the chassis and on the rear part 3 b of the rear element 3.

[0021] In the variant depicted in FIG. 3, the front element 1 is connected to the intermediate element 2 in the same way as in the version according to FIG. 2.

[0022] Likewise, as in the case of FIG. 2, the rear element 3 is moved by an articulated arm 6 and its rear part slides in a slide 18.

[0023] On the other hand, the rear element 3 does not have any slide. It is connected to the rear element by two articulated levers 19, 20, one of which 20 is connected in an articulated fashion by a link 21 to the arm 6.

[0024] The version of the retractable roof depicted in FIG. 2 functions as follows:

[0025] After unlocking of the elements 1, 2, 3 and opening of the lid 5 a of the boot 5, the arm 6, whose pivoting is controlled by a motor or an actuator, moves the rear element 3 towards the boot 5. This movement is guided by the finger 17, which slides in the slide 18.

[0026] The arm 6 in its movement makes the lever 13 connected to the element 2 pivot towards the rear, by means of the link 14. Likewise, the lever 13 drives in its movement, by virtue of the link 16, the lever 15 connected to the element 1. The tilting of the levers 13 and 15 pushes the elements 2 and 1 respectively in the slides 11 and 9 so that the elements 1, 2, 3 are progressively superimposed and then come to be stored substantially horizontally in the boot 5 as indicated in FIG. 4.

[0027] In the case of FIG. 3, the rear 3 and front 1 elements move in the same way as in the case of FIG. 2.

[0028] The intermediate element 2 is moved upwards and is progressively superimposed on the rear element 3 by virtue of the levers 19, 20, whose upward pivoting is controlled by the link 21, which is driven by the arm 6.

[0029] In a simplified version of the invention, particularly in the case of coupés having only two seats, the retractable roof could include only the two elements 2 and 3. 

1. A retractable roof for a vehicle, comprising a front roof element (1), an intermediate roof element (2) and a rear roof element (3), these three elements being able to move between a position in which they cover the vehicle cabin (4) and a position in which they are superimposed substantially horizontally in the rear boot (5) of the vehicle, characterised in that the movement of the rear element (3) towards the boot is controlled by at least one arm articulated on the chassis of the vehicle and on the rear element, in that the rear element (3) comprises a slide (9) extending between its front and rear edges in which there can engage a finger (10) fixed to the rear edge of the intermediate element (2) so that the intermediate element (2) can slide on the rear element (3), in that the intermediate element (2) also comprises a slide (11) extending between its front and rear edges in which there can engage a finger (12) fixed to the rear edge of the front element (1) so that the front element (1) can slide on the intermediate element (2), in that the front edge of the rear element (3) is connected in an articulated fashion to the intermediate element (2) by means of a lever (13) which is itself connected in an articulated fashion to the arm (6) by a link (14) and in that the front edge of the intermediate element (2) is connected in an articulated fashion to the front element (1) by a lever (15) which is itself connected in an articulated fashion by a link (16) to the lever (13) which connects the intermediate element (2) to the front element (1).
 2. A retractable roof according to claim 1, characterised in that the movement of the rear element (3) towards the boot (5) is also controlled by a finger (17) carried by the rear part of the rear element (3) slidably engaged in a slide (18) extending inside the boot (5).
